Title: Sealed lining tube for lining of pipelines or passageways
Inventor: SMITH EDWARD PETER
IPC: F16L59/147
Filed: 1990-08-27
Abstract: The method provides that a lining tube impregnated with synthetic resin is applied to the inner surface of a pipeline or passageway to line same. A pre-lining tube is either connected to the leading end of the lining tube so that the lining tube can be inserted by everting the pre-lining tube into the pipeline or passageway which pulls the lining tube into position, or the lining tube is connected at its trailing end to an inflation tube which is pulled into position as the lining tube enters the pipeline or passageway and subsequently the inflation tube is everted into the inside of the lining tube to inflate same. In the preferred case the assembly comprises a pre-lining tube connected at the leading end to the lining tube, and an inflation tube connected at the trailing end of the lining tube.

Title: Method of processing, storing and utilizing sheets of elastomeric coated cords
Inventor: MAGNUS FREDRICK L
IPC: B60C9/22
Filed: 1990-09-10
Abstract: ABSTRACT OF THE DISCLOSURE A METHOD OF PROCESSING, STORING AND UTILIZING      SHEETS OF ELASTOMERIC COATED CORDS     A method of producing sheets (48) of elastomeric coated cords (40) for use in the building of laminated rubber articles such as tires is disclosed.  The process eliminates the use of polyethylene liners in the manufacture and storage of the sheets.  Composite elastomeric sheets are produced having cords (40) on one side and an unvulcanized elastomer (44) on the other side.  The tack of the unvulcanized elastomer is reduced after calendering such that the sheet can be rolled up upon itself, without the use of a liner, and unrolled such that it will self-release.  The above method is especially adapted for the manufacture of strips of sheets for use as overlays in tires.

Title: A transfer device
Inventor: MURPHY JAMES F
IPC: E05G7/00
Filed: 1990-09-12
Abstract: ABSTRACT           A security transfer device 1 for mounting on a side wall of a building such as a bank for example for transferring valuables between a vehicle and the building.  The security transfer device 1 comprises a duct 2 slidably mounted in a housing 3 secured in a wall 23 of the building and movable between a retracted stored position within the housing 3 and an extended in-use position projecting outwardly of the housing 3.  A releasable ratchet mechanism 4 extends between the duct 2 and housing 3.  When engaged the ratchet mechanism only permits outward movement of the duct 2, thus preventing the duct 2 from being pushed back into the housing from outside the building.  A lockable door 12 closes an inner end of the housing 3.  The duct 2 is also closed at it's rear end 19 by a lockable security door 20.

Title: Cold pressure welding method and machine
Inventor: HAWKES DANIEL J
IPC: B23K20/02
Filed: 1990-03-02
Abstract: (57) Abstract The machine is provided with a set of two pairs of die halves (60, 62) mounted in a framework on hydraulically actuated pist    and cylinder assemblies. The die halves (60 and 62) of each pair are relatively radially reciprocable to grip or release a wo   ?ce (102, 104) and the two pairs of die halves are relatively axially reciprocable to effect cold pressure welding together of end portions of the workpieces (102, 104). Adjoining end faces of the die halves are formed with nose portions (100) having inner anvil edges for effecting welding flash removal from the workpieces. In operation, the die halves are moved in sequence to grip the workpieces; to urge the ends of the workpieces together to form a cold pressure weld upset zone; to release the workpieces; to grip one of the workpieces; to urge the gripped workpiece axially relative to a pair of anvil edges to clear flash material from the upset to maintain the cross-sectional area at the weld upset zone substantially constant; and to re-position the upset weld zone centrally of the nose portions to repeat the sequence. Removal of the flash material intermediate consecutive weld upsets is effect-ed in alternate directions. The anvil edges may be staggered, angled or of helical form to enhance the shearing effect to clear the flash material from the upset weld zone.

Title: Multiport - multipoint digital data service
Inventor: BASNUEVO ROGELIO J
IPC: H04J3/22
Filed: 1990-12-24
Abstract: ABSTRACT      In a Digital Data System (DDS) a method and apparatus for providing multipoint multiport service.  Differences in time delays through the network are compensated by an alignment training wherein the delays from each remote station are measured at a Central station.   The Central station determines how much delay to insert at each remote station and then instructs the remote stations to insert the delays.  This allows all inbound data to be aligned in time so that when the data are combined within the network by the Multipoint  Junction  Units  (MJU)  data  errors  are  not produced.  Aligned frames are combined in the MJU operating in data mode in a logical AND operation so that marks transmitted by inactive ports are combined with data from active ports to produce a composite signal which is passed to the Central DSU.

Patent CA-2049889-A1 (CA)
IPC: F24F5/00
Filed: 1991-08-26
Abstract: The method stores heat in ice by freezing water through its direct contact with a hardly-water-soluble refrigerant; i.e., water is mixed with the refrigerant at a high pressure to produce a liquid mixture while preventing evaporation of the refrigerant, and the liquid mixture is jetted from a nozzle into a space at a lower pressure, whereby the refrig-erant evaporates at the lower pressure and the water in the liquid mixture is frozen into sherbet-like ice and dispersed over a wider area than in the case of non-sherbert-like ice. A device based on the method uses a heat-insulating water tank whose top space above water level therein is kept at a pressure P2 lower than saturation pressure P0 (P2<P0) of the refrigerant for water freezing point 0°C.  A mixer mixes the refrigerant of liquid phase and water at a pressure P1 which is higher than the saturation pressure P0 of the refrigerant for water freezing point 0°C (P0<P1), so as to produce a liquid mixture without allowing evaporation of the refriger-ant.  A nozzle having an opening in the top space of the water tank jets the thus prepared liquid mixture to the top space at the pressure P2, whereby the refrigerant evaporates so as to freeze the water of the liquid mixture into sherbet-like ice.

Abstract: A thermoplastic  pressure  vessel  consisting  of  a container having an exterior sidewall,  a bottom and an annular top rim.  An annular seal surface encircles the top rim.  An annular collar extends outwardly and downwardly from the sidewall adjacent the top rim.   The downward portion of the collar is spaced from and substantially parallel to the sidewall of the container such that an air cavity is formed between the collar and the sidewall.  The collar has a threaded exterior surface.   A closure is provided having a top with a depending annular skirt.  The skirt has an upper portion of a first diameter with an interior sealing surface and a lower portion of a second diameter larger than the first diameter having a threaded interior surface.  When the closure is positioned on the container the interior sealing surface of the upper portion engages the seal surface on the side of the top rim and the threaded interior surface on the lower portion of the skirt engages the threaded exterior surface on the collar to form a threaded connection thereby maintaining contact between the seal surfaces.  The threaded connection is partially insulated by the air cavity from inward and outward flexing of  the  sidewalls  of  the  container  resulting  from differentials  in  pressure,  and  is  capable  of  limited flexion to maintain contact between the seal surfaces when such flexing occurs.
